To all whom it may concern:

Be it known that I, EDWARD V AN Hoor STADT, a subject of the King of Belgium, residing at 280 Fort Washington Ave, New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Package- Filling Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in machines for filling boxes, packages or cartons and more particularly has reference to and is illustrated in the accompanying drawings in the application of the invention to a machine for filling cartons and packages with matches suitable for carrying'in the vest pocket.

In the accompanying drawings, Figure 1 illustrates an application of my invention inside elevation as applied as aforesaid. Fig. 2 is a plan view with parts broken away; Fig. 8 an enlarged'detail in side olevation showing the mechanism for feeding the blanks into the machine; Fig. i is an enlarged detail of part of the box-gripping mechanism; Fig. 5 is an enlarged detail of a part of the box-folding mechanism; Fig. 6 an enlarged detail of partof the stitching mechanism; Fig. 7 a plan view of the box in blank form; Fig. 8 an enlarged detail of part of the box-folding mechanism; Fig. 9 an enlarged detail of the apron. operating mechanism';l ig. 10 a plan view of part of the apron, Fig. 11' a cross-sectional view on the line 1l,1l of Fig. 10, and Fig. 12 is an enlarged detail of parts shown in Fig. 8.

12 is the drive shaft provided with he usual form of pulley 13 and belt 1 1 and provided with the worm such as 16 which engages the pinion 17 on the shaft 18. Said shaft 18 is also provided with a sprocket 19 having a chain 20 driving the sprocket 21 upon the shaft 22 which also drives the shaft 23 through the pinions 2425. Upon the shaft 23 is the cam 26 upon which rides the roller 27 mounted on the end of the bell-crank 28 which is pivoted at 29 in the bracket 30 upon the frame of the machine as shown. At the upper end of the bellcrank is pivotally mounted the connector 31 which receives the end of the screw 32 which is fastened 'therein by the nut 33 after the same has been adjusted. The opposite end of the screw member 32 is pivot-ally mounted at 34 in the bracket 35 beneath the frame of the machine as shown, and the bracket is secured to a centrally movable portion 36 adapted to reciprocate beneath the guides 37 through which the blanks of the boxes such as shown in Fig. 7 are fed by gravity. The movable table 36 it will be observed is also provided with aslight projection such as 38 adapted to engage the bottom box or blank of the stack, so that as the earn 35 rotates rightwardly looking at Fig. 3, the lower arm of the hell-crank 38 is thrown upwardly and through the connections aforesaid, the table 86 is shifted loftwardly, the projection 38 engaging the rigl hand edge of the bottom blank and shifting the some leftwardly beneath. the stack, the advanced of the blank being slightly elevated by the resilient member or spring 89.

The shaft 18 it will he observed by reference to 3 is also provided with the cam such as 40 adapted to ride against the roller i1 upon the lever 42 which pivoted at 4:3 upon the bracket 4 also attached to the frame of the machine and the upper end of the lever is pivotally connected to the rod l?) which in turn is pivotally connected. to the carriage 46 adapted to slide upon the bearing 47, said carriage -16 being provided with the bearing i7 upon which is pivot ally mounted the lever 48 normally projccted upwardly by 1 rent means such as the spring 429. 5-0 is a hood or hearing the under surface of; which is adapted to be engaged by the roller at the upper eX- treniity or the lever 1:8, and the. lower-end of the lever a8 is pr videcl with the finger 52, and a u' such as 533 is also secured age 4-6 so that as the cam l0 to the carrotates, the upper end of the lever 42 is thrown rightwardiy ag st the action of the spring 5i thereby ving the carriage 46 rightwardly, the roller 51 engaging'beneath the hood raises the finger 52 until the finger 53 has traveled rightwardly suiiiciently to pass beneath the left edge of the blank which has been elevated by the resilient member as aforesaid. As the carriage 4-6 new returns leftwardly, the roller 51 riding upwardly over the top of the hood 56 causes the finger 52 to depress upon the edge of the blank which is caught between. the same i i the linger 53 and is brought leftwerdly in. position upon the ally mounted at 61 upon the frame of the machine as shown.

62 is a suitable spring secured upon the machine at 63 and to the lever 60 at 64 as shown, and 65 is a lever pivotally connected at the lower end of. the lever 60 and to the lever 66 at its opposite extremity as shown, said lever 66 being adapted to rotate upon the shaft 67. The lever 66 it will be observed also carries the pawl 68 adapted to engage the teeth 69 in the ratchet.70 secured to the shaft 67 thereby rotating the sprocket wheel 71 and the apron 72 adapted to engage the same by the pins 73 thereof. By referring now to Fig. 3 it will be observed that said apronis also pro-- vided with resilient fingers such as 7e: beneath which the blank is drawn by the hn gers 5253 as aforesaid, so that from theforegoing it will be readily understood that each blank is successively drawn from the bottom of the stack by the table 36 from which the blank is taken by the fingers 5258 and drawn beneath the fingers 7% upon the endless belt 7 2 at which point thebox is moved at right angles through the medium of the. transmission described in connection with Fig. 9.

Referring now to Fig. 5 it will be observed that the shaft 18 is provided with a cam 75 upon which rides the roller 7 6 pivotally mounted upon the rod 77, the lower extremity of which is formed in a frame-like structure 78 surrounding said shaft 18 and the upper extremity of which is pivotally connected to the rod 79 terminating in the presser foot 80, the same being pivoted at 81 upon the bracket 82 secured to the frame of the machine, and 83 is a suitable spring also secured to the frame of the machine and at 84: as shown, so that as the'cam 75 rotates it will be readily observed that the presser foot rises and falls as indicated in dotted outline. 85 is another depending lever pivotally mounted at 86 and provided at its lower extremity with a roller 87 adapted to ride upon the face of the cam 88, and the upper end of the lever 88 being pivotally connected at 86 to the lever 90 which'is pivotally mounted 'at' 91 in the bracket 92 causes the inner. end of said lever 90 to reciprocate vertically and at this point theU- shaped former 93 is pivotally secured thereto as indicated at 94. From tne foregoing it will-be observed that as the blank is fed. rightwardly upon the apron lookin at Fig. 2 when it comes beneath the presser foot 80 the same descends firmly holding the same in position while the U-sh'aped former 93 rises beneath the same, thereupon turning up the outer sides 95- 95 of the blank. yo

the lines of the ridges 96'97 the intervene o ing spaces between said ridges serving as the sides of the box orpaekage when com-- pletely formed. From beneath thefpresser foot 80 the blank is now carried beneath the flattening member 98 and continues rightwardly looking at Fig. 2 until it reaches thestop 99 shown in Fig. 1., said stop 99 being of course in its lowered position.- Said stop isslidably mounted inthe guideslOO and is slidably driven therein by the lever 101 at the oppoe site extremity of which is mounted the roller 102 adapted to ride upon the cam 103 upon the shaft 22. l I

104 indicates an endless apron provided 5 with partitions such as 105 between'whieh thematches are fed automatically or manu ally as may be desired. This apron is intermittently driven by the shaft 23 and passes over the pulleys 106, and 107 as shown. After the blank has reached the'stop99 as aforesaid the pusher member 108 mounted withinthe slide bearings 109 passes rightwardly looking at Fig-1 driving the matches between the partitions which are in front 105 of the pusher 108 into position. upon the blank. To accomplish this result the pusher 108 is pivotally connected at the top of the lever 110 which is pivotally mounted at 111. and provided at the lower extremity with. no the roller 112 which feeds upon the cam 113, said lever 110 being retained against the cam by the spring such as 114, the earn 113 being mounted upon the shaft 18 as shown.

Afterthe matches have been pushed intodlo position upon the blank, the stop 99 lifts, allowing the apron to continue rightwardly carrying the blank beneath the guides 115 which turn the sides up and over in closed position.

The box now partly folded or closed is again shifted at right angles by'the plunger 116 which is pivotally mounted at the-end of the lever 117 having pivotal bearing at 118. The lever 117 is also pivotally com nected at 119to the rod 120 at the lower ex .tremity of which is mounted the roller 121 adapted to ride upon the cam 122 upon the shaft 22 by the tension spring 146 so that as the earn 122 revolves the rod 120 is reciproeated thereby reciprocating the lever 117 and the plunger 116 which, moving in the path in which the filled box has been placed by the apron, shovesthe box in the direction of the observer looking at Fig. 2 until it rests upon the elevator 123. This elevator is vertically reciprocatable by the bell-crank 124 which drives the same between the guides 125 .and which is pivoted at 126 to the frame and at the opposite extremity of which is provided the roller 127 adapted to ride upon the cam 128 on the shaft 22. After the elevator has descended and the box has shifted therefrom the stacker 129 pivoted at 130 having a roller 131 atthe oppo site end engaged by the projection 132 of the lever 120 stacks the matches evenly within the box so that as the box travels in the direction of the observer looking at Fig. 2 the larger end is engaged beneath the guide or folding member 133 and is laid over following which the smaller end is engaged by the folding member 134 and is also laid over the box of matches continuing to pass in the direction of the observer until the lower end of the box passes beneath the opening 135 at which point it is in position to be secured or stitched.

By reference now more particularly to Fig. 6 it will be observed that the plunger 136 of the usual form of stitcher shown at the upper right hand portion of Fi 1 delivers the wire above the lower en of the box 137 and having driven the same as shown, the cam 138 upon the shaft 139 lifts the slide 140 by its roller 141 until the same strikes the member 142, the upper portion of which lifts the, clamping fingers 143 and 144 thereby turning the ends of the wire stitch inwardly and thereafter the cam 146 which also engages the roller 141 drives the member 142 still farther upwardly until the clamping fingers 143 and 144 lay the ends 145 flatly against the outside of the box thereby securely stitching the same in closed position.

Of course it will understood that various changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

I claim:

1. In a machine of the class described means for feeding blanks successively from beneath a stack upon a conveyer moving at an angle thereto means for forming. a box while passing along said conveyer, means for feeding material into said box while upon said conveyer, meansfor folding the stitching the same in place, said jmaterial feeding means operating at right angles to I said conveyer.

3. In a machine of the class described,

means for feeding blanks successively from beneath a stack upon a conveyer moving at an angle thereto, means for forming a box while passing along said conveyer, means for feeding material into said box while upon said conveyer, means for folding the sides of said box thereafter and means for then turning over the ends of said box and stitching the same in place, said material feeding means operating at right angles to said conveyer, and saidend-turning means at right angles to said conveying means.

In testimony whereof I hereunto aiiix my signature in the presence of two witnesses. EDW'ARD VAN HOOFSTADT. Witnesses:
